Abstract

A signal layer rectangular microstrip antenna embedded with open-ended and close-ended slots is presented in this paper. Two open-ended slots are introduced inside the ground plane as well as inside the patch to excite the antenna with different resonant mode. In another configuration, two close-ended slots are introduced both inside the ground plane and patch to observe the variation in resonant frequency and bandwidth of the antenna. The proposed structure showed promising results in perspective of return loss, gain, efficiency and directivity for the applications wireless communication system including IEEE 802.11a WLANs application that allocate channels between 5.15 to 5.825 GHz.
